4 写个controller测试
//操作ip
String operIp = IpUtils.getIpAddr();
String region = IpAddressUtils.getRegion(operIp);
System.out.println("operIp = " + operIp);
System.out.println("region = " + region);
System.out.println();
String region1 = IpAddressUtils.getRegion("117.28.182.162");
System.out.println(region1);
效果如下
operIp = 127.0.0.1
region = 内网IP
